CENTRIFUGAL CREAM ER.

SPECIFICTION forming part of Letters Patent No. 697,170, dated April 8,1902.

Application filed August 6, 1901. Serial No. 71,102. (No model.)

To fZZZ uf/Loin it may concern:

Be itknown that we, HERMANN RECK,asub ject of the King of Great Britain,residing at l Ilolborn Circus, in the city of London, England, andANATOLE BORSU, a subject of the King of Belgium, residing at Falkstrasse4, Bielefeld, in the Empire of Germany, have invented certainImprovements in Centrifugal Creamers,ofwhich the following is aspeciiieation. A

The invention relates to that class of centrifugal machines adapted forseparating two liquids of different densities from their mixture; and itis primarily designed to facilitate the separation of cream from thewhole milk, so called. In the claims hereto appended the preciseimprovement will be set out in connection with the accompanyingdrawings, in which- Figure l is a vert-ical section of the separator.cylinder which incloses a divided liner. Fig. 3 is an elevation of thedivided liner, and Fig. at is a plan View thereof.

Referring irst to Fig. l, the drum Z, provided with a cover, is rotatedin a suitable casing. g is a sleeve to which are attached the ribs CZ.This sleeve is formed of a hollow cylinder which when placed over thecentral section of the bowl forms a passage for the whole milk, whichpasses thence through'the delivery-tubes 7L h into the bowl. Outlets areprovided for the skim-milk through the tubes m n, and for the cream at7o through the screws shown, these latter being adjustable to'allow ofthe thickness of the cream-layer being varied. a a are the plates, whichare shown in this case fourin numberand tapered vertically, so as to benearer the central sleeve g at the top than at the bottom. They areattached to this sleeve g by means of the ribs d, and are furtherconnected with each other by pieces b l) l), so that the one plate isheld apart from the other and so that one edge fis held nearer to thecenter of the bowl than the other edge e. As to which edge is the nearerto the center depends upon the direction in which the bowl is rotated,being, as shown at e and f, when the direction is that indicated by thearrow in Fig. 4. On

Fig. 2 is an elevation of a corrugatedr the outside ot' the plates awings c are provided, which may either adjoin the edge e, as shown, ormay be attached in any other suitable position on the outer surface ofeach plate. The bottom edges of the plates are bent so as to forni aiiange q, on which rests the perforated cylindrical covering t, and thisin conjunction with the wings c divide the interior o f the bowl into aseries of cells, thus preventing the readmixture of the milk and creamparticles after once being separated. These plates may be of a largernumber than four in larger-sized machines.

The whole milk enters the bowl through the tubes h, as shown by thearrows, when it immediately flies against the plates a if the bowl isempty and gradually proceeds to iill the bowl. The free surface of theliquid approaching the center is a vertical and approximatelya straightline if the drum is revolving at full speed. When the vertical line ofliquid approaches as near to the center as the outlets le and n, creamand skim-milk, respectively, will immediately issue therefrom. When thebowl is revolving under normal conditions, it will be filled to thevertical level of the outlets, when the Whole milk enters at h andseparation will begin almost immediately, the lighterglobules of creamgoing at once to the center and the skim-milk passing outward until itmeet-s the plates a, when it is directed either down under the iiange qor out through the slots between the edges ef. In the former case itisthe most easilyseparated milk which passes to the outside of thecylindrical cover i and rising in the space between the cover and theside of the bowl reaches the mouth of the outlet-tubes m. The milkpassing through the upright slots is not wholly separated and undergoesa further separative action in the space between the plates a and thecover, which is divided into cells by the wings c. The cream particleshere separated pass up the slanting surface of the plates a to the topof the creamcolumn, and the whole milk passes out of these spacesthrough the perforations in the cover t.

The cover is prevented from turning relatively to the plates by asuitable holding device, such as the slot o, in which one of the vwingsc can slide.

their upper ends with said sleeve, said plates also being inclinedupwardly toward said sleeve and forming 'a diyided l/iner having slotsextending froufhase to top of the liner, and suitably connectedtogether, substantially as set forth.

2. .In acentrifugal separating-machine, the combination of a rotatingbowl and a central feed-sleeve having a series of arcual plates providedwith radial ribs connecting them to said sleeve and inclined upwardlyand toward said sleeve, and forming a divided liner having slotsextending from th`e base to the top of the liner, said plates beingconnected upon opposite sides of said slots by shortpieces,substantially as set forth.

3. In a centrifugal separating-machine, the combination of a rotatingbowl and a central feed-sleeve having a series of arenal plates inclinedupwardly and toward said sleeve and having slots therebetween, alsohaving radial ribs connectingthe edges of said plates nearest the centerof the bowl with the said central sleeve, forminga series ofpartially-closed cells, around said central sleeve, connected with thespace outside ot' the liner-plates by said slots.

4. In acentrifugal separating-machine, the combination of a rotatingbowl and a central feed-sleeve having a series of arenal plates providedWith radial ribs connecting them to said sleeve and inclined upwardlyand toward said sleeve, said plates forming a divided liner withlongitudinal slots between the edges of the plates, and radial wingsattached to the exterior edges of said linerplates, farthest from thecenter of the bowl.

5. Ina centrifugal separating-machine, the combination of a rotatingbowl and a central feed-sleeve having a series of horizontallycurvedplates connected by radial ribs to said sleeve and inclined upwardly andhorizontally toward said sleeve, said plates forming a divided linerwith longitudinal slots between the edges of the plates, and radialwings attached to the exterior surface of said plates.

6. In a centrifugal separating-machine, the combination of a rotatingbowl,a central feedsleeve having a series of horizontally-curved platesconnected by radial ribs to said sleeve and inclined upwardly and towardsaid sleeve, said plates forming a divided liner with 1ongtudinal slotsbetween theedges of the plates, and a perforated cylindrical coverinclosing said liner-plates, open at its upper end and mounted on thelower edges of the plates, and separate outlets for the cream and milk.

7. In a centrifugal separating-machine, the combination of a rotatingbowl and a central feed-sleeve having a series of horizontallycurvedplates connected by radial ribs to said sleeve and inclined upwardly andtoward said sleeve, said plates forming a divided liner, radial wingsattached'thereto, a perforated cylindrical `cover inclosing said linerand forming, with said wings, partiallyclosed cells, said plates havingbetween them longitudinal slots connecting the cells on the interiorwith those on the exterior of said liner.

8. In a centrifugal separating-machine, the combination ofa rotatingbowl, a central feedsleeve having a series of horizontally-curved platesconnected by radial ribs to said sleeve and inclined upwardly and towardsaidsleeve, said plates forming a divided liner, with longitudinal slotsbetween the edges of the plates, radial wings attached to said plates, acorrugated cylindrical cover inclosing said plates and havingperforations in the depressions and ridges of the corrugations, outletsat the top of the bowl for the cream, and pipes having their inlet atthe top of the bowl and their outlet at the bottom of the bowl for theoutflow of the skimmed milk.

In testimony whereof we have signed our names to this specification inthe presence of the subscribing witnesses.
